A conceptual design for a small-scale green ammonia plant is presented in which synthesis was realised via Haber-Bosch loop using hydrogen produced by solid oxide electrolyser and nitrogen purified from air with series of electrolyte oxygen pumps. The system operated an energetic efficiency 52.12%, very close to cryogenic ASU reference where 52.89% achieved. specific energy consumption 9.94 kWh...

Storing renewable energy in chemicals, like hydrogen, can bring various benefits high density, seasonal storability, possible cost reduction of the final product, and potential to let power penetrate other markets overcome their intermittent availability. In last year’s production this gas from sources via electrolysis has grown its reputation as one feasible solution satisfy future zero-emissi...

Stainless steel interconnect materials used in solid oxide fuel cells and electrolysers need to be coated improve oxidation resistance mitigate Cr-vaporization. This work aimed explore the optimal steel/coating combinations suitable for use reversible stacks evaluated (Co,Mn)3O4 spinel, LaFeO3 perovskite, Ce/Co Y-based coatings, on AISI441 Crofer 22 APU steels. The coatings were based measureme...
